Definitions

  • the present invention relates to filling systems for vehicle fuel tanks and particularly tanks of the type which have a remotely accessible filler tube, for example, of the type accessible through a fuel filler door mounted on the side of the vehicle.
  • Fuel tank installations of this sort are commonly employed on passenger cars and light trucks where it is desired to have the fuel tank filler recessed within the vehicle body and covered by a filler door which blends with the side structure of the vehicle for esthetic or styling purposes.
  • Vehicle fuel tank filler systems require a positive seal of the filler tube or “neck” when the filler nozzle is removed in order to meet mandatory fuel vapor emission requirements; and, thus it has been the practice to provide a one-way valve, typically in the form of a flapper door valve to close the filler tube when fuel is not being introduced to the filler tube during refueling.
  • the present invention provides a solution to the above-described problem of designing a fuel filler tube or neck assembly including a one-way check valve which may be pre-assembled to the fuel tank and including a nozzle receiving receptacle on the end of the filler tube.
  • the filler tube assembly of the present invention includes a one-way valve for check valve and may be pre-assembled to either a metal fuel tank or a plastic fuel tank.
  • the filler tube assembly including the one-way check valve of the present invention readily accepts a siphon hose inserted through the filler nozzle receiving receptacle end of the filler tube assembly and permits passage of the siphon hose through the one-way valve into the fuel tank without the risk of the end of the siphon hose being caught or sticking in the one-way valve or damaging the elastomeric seal for the one-way valve.
  • FIG. 1 is a cross-section of a portion of a metal fuel tank having the filler tube and check valve assembly of the present invention attached thereto;
  • FIG. 2 is a view similar to FIG. 1 of an alternate embodiment of the invention installed on a plastic fuel tank;

  • the upper end of the tube 20 extends outwardly of the tank and has received thereover a filler hose, preferably of elastomeric material as denoted by reference numeral 24 with the lower end thereof received over the upper end of tube 20 .
  • the upper end of the hose 24 may have received therein a nozzle receiving receptacle tube 26 which has the upper end thereof open and adapted for receiving therein a refueling nozzle (not shown).
  • valve 18 is shown in cross-section and enlarged and includes a tubular body 28 having the upper end thereof provided with an annular barb with a seal ring groove 30 formed therein; and, an annular mounting flange 32 may be provided if desired, intermediate the ends of tube 28 and below the seal ring groove 30 .
  • the inner periphery of the tube 28 has at least one and preferably a plurality of circumferentially spaced radially inwardly extending ribs 34 formed therein.
  • the lower end of the tube 28 has a projection 36 extending outwardly therefrom and circumferentially aligned with ribs 34 .
  • the projection 36 has formed therein a slot 38 which is elongated in the axial direction of the tube and which has received therein a torsion spring 40 which has one end thereof extending radially inwardly over the end of the tube 28 .
  • the tube 28 is preferably formed of plastic and may have electrically conductive material interspersed therein for facilitating discharge of accumulated static electrical charge.
  • a moveable valve member which may be configured as a flapper is indicated generally at 50 and is disposed over the end of the tube 28 and has an annular resilient preferably elastomeric seal 52 secured about the periphery thereof for sealing contact with the lower end of the tube 28 .
  • the valve member 50 has a pair of arms 54 extending outwardly therefrom on opposite sides of the valve member 50 with each of the arms having an inwardly extending trunnion 56 formed thereon.
  • each of the arms 54 is deflected; and, the trunnions 56 are each respectively engaged in an opposite end of the slot 38 on the projection 36 thereby forming hinges for pivotal movement of the valve member 50 about the end of the tube 28 .
  • a partially circumferentially extending shield or shroud 58 may be formed about the lower end opening of the tube 28 and about the valve member 50 .
  • the inwardly extending end 41 of the torsion spring slidably engages a raised contact surface 60 (see FIG. 6) provided on the outer face of the valve member 50 .
  • the valve 50 includes a deflector rib 61 formed on the inside surface thereof and which serves to provide a camming action to open the valve upon insertion of a siphoning hose, indicated in dashed outline and denoted by reference numeral 62 in FIG. 3.
  • Ribs 34 and 61 serve to direct the siphoning hose away from seal 52 thereby preventing the base from catching on or damaging the hose.
  • an alternate system indicated generally at 100 employing the present invention is illustrated as a plastic fuel tank 102 having an access opening 104 formed in a portion of the upper wall thereof through which is inserted a filler tube assembly indicated generally at 106 which includes a one-way or check valve assembly indicated generally at 108 and a hose 110 with the lower end thereof received over a portion of the valve assembly extending externally of the tank; and, a filler nozzle receptacle tube 112 adapted for connection to the vehicle structure is attached to the upper end of hose 110 .
  • the one-way valve assembly 108 is shown in enlarged detail as having a valve body with a generally tubular configuration as denoted by reference numeral 114 with the upper end thereof having an annular barb 116 formed thereon and a seal ring groove 118 formed therein intermediate the ends thereof with a seal ring 120 received therein.
  • An annular flange 122 may be formed about the outer periphery of the tubular member 114 intermediate the seal groove 118 and the lower end of the tube.
  • a mounting member 124 preferably with an elongated tubular configuration has one end thereof sized and configured to be received over the annular barb 116 of valve tube 114 ; and, the tubular mounting member 124 has the inner periphery thereof sealing over the ring 120 on the valve tube 114 .
  • the lower end of the tubular member 124 is registered against one axial face of the flange 122 .
  • the upper end of the tubular member 124 or end opposite the flange 122 may have an annular barb 126 formed thereon for engaging the end of the hose 110 (FIG. 2) in fluid sealing engagement.
  • the annular mounting member or tube 124 has a radially outwardly extending flange 128 formed about the outer periphery thereof and located axially intermediate the ends of the member 124 .
  • the flange 128 may be located at other positions on the tubular member 124 as, for example, at the lower end thereof if desired.
  • the flange 128 has an annular seal member 130 , preferably formed of elastomeric material, disposed about the periphery thereof adjacent the underside of the flange; and, the seal 130 may be retained thereon by a retaining ring 132 having its inner periphery frictionally engaging a shoulder 129 provided on the tubular member 124 .
